Subject: [PATCH] Print logo should use an absolute URI

The logo is configured as a relative URL.
CSSMin encodeImageAsDataURI requires a file path.

There seems to be no reason to use a data uri here.
The print stylesheet is loaded on page load so the image
will be downloaded before a print action takes place.

Inspecting I788bcecadf26e4e5558b5b37e6fb1b2e9378277e
using a data uri makes little difference to the synchronous
nature of a print.
